Former Swansea City manager Garry Monk has backed Jonjo Shelvey to justify his transfer fee at Newcastle United.

The 23-year old signed for the Magpies for £12million in January and after working alongside him at the Liberty Stadium, Monk has backed the English midfielder to succeed at St Jams' Park.

"Jonjo was a big part of what I did there and, of course, that consistency with him is what you're looking for," Monk said on Sky Sports Goals on Sunday.

"You forget how young Jonjo is. He's got his peak years ahead of him and I think, once he learns that consistency in his game, you'll see what he can do.

"He's got that magic ability to be able to pick passes. He can be a match-winner. That's the key, but he needs to get that consistency in his game.

"I'm sure going to a club like Newcastle in front of that many fans and that type of club will suit him.

"A lot to do with Jonjo is motivation. He needs to be performing every single week and feel importance as a player. Newcastle will probably give him that.

"It will be interesting to see. I'm sure he will go there and do well."
